TAYLOR E. DANIELS, OF CHICAGO, ILLINOIS.
STEAM FE E D COOKER AND DRIER.
SPECIFICATION forming part of Letters Patent No. 235,343, dated December 14, 1880. Application filed September 28, 1880. (No model.)
To all whom it may concern:
Be it known that I, TAYLOR E. DANIELS, a citizen of the United States, residing'atChica-go, 1n the'county of Cook and State'of Illinois, have invented certain new and useful Improvements in Steam Feed Cookers and Driers; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, of which-.
Figure 1 is a side elevation of the apparatus wlth certain portions broken "away, showing the interior construction; Figs. 2 and3, oppos te end views; Fig. 4, a vertical cross-sectron of the apparatus; and Fig. 5, a detail section showing the construction of the jet-pipes whlch convey steam into the cooking-cylinder.
My present invention relates to certain improvements upon the apparatus described in Letters Patent of theUnited States No. 225,511, granted to me March 16, 1880. p Theseimprovements consist,'first, in employmg, instead of the vertical cooker with conelike steam-discharging stirrers described in the Letters Patent aforesaid, one or more horizontal screw conveyers inclosed within cylinders similar to those employed in the drler, and communicating with the said'cylinders of the drier in the same manner as the latter communicate with one another, together w1th appliances for injecting steam into the Interior of the grain as it is carried through the cylinder; secondly, in providing a hot-air flue upon the lower face of each cylinder of the drier, communicating with the interior of said cylinder through perforations in said cylruder; thirdly, in the exhaust which I employ for carrying off the vapors which arise within the cylinders of the drier; and, furthermore, in certain details of construction-a1l as hereinafter more fully set forth.
In the drawings, A is the case of the apparatus; B B, the three pairs of horizontal cyllnders of the drier communicating with one another at alternate ends through vertical passages '11, and the lowest pair having discharge-chutes c, all this being substantially the same as in my said former Letters Patent, find hence requiring no particular description ere.
O C are the screw-conveyers lying within the cylinders B, and having hollow shafts journaled into the ends of the case A, and revolved by means of gear-wheels a, operated in common by a pulley upon the shaft D, all this being also substantially as described in my said former Letters Patent, except that I now perforate the shafts of the conveyers and force hot air into them instead of steam, as will be hereinafter explained.
E E are gates of steam-pipe, which I now prefer to arrange edgewise upon both sides of the cylinders B, as shown, and preferably curved, so as to lie against the cylinders instead of above and below them, as formerly, th eir function, however, remaining unchanged.
The functions and operation of this much of my apparatus being fully described in the specification of my said Letters Patent No. 225,511, I shall now proceed to describe my present improvements, beginning with the cooker.
B B are two horizontal hollow cylinders extending from end to end of the case A, and corresponding to those of the drier below them. Each has a feed-chute, t, at one end, and communicates with the cylinder B beneath it by means of a chute, v, at the opposite end, in the same manner as the cylinders B communicate with one another.
0 is a screw-conveyer within each cylinder B, and journaled in the ends of the case A. Both the shaft and blade-of this conveyer are hollow, and their interiors communicate, as clearly shown in Fig. 4. The blade of this conveyer is provided with perforations s.
F is a pipe, which is to be connected with a suitable steam-generator, and branches of this pipe lead both into the hollow shafts of the screw-conveyors O and into the uppermost gates of pipe E.
G G are pipes leading from the steam-pipe F, and extending across the interior of the case A parallel with the cylinders B, and a short distance below them. The interiors of the pipes G and cylinders B communicate with each other through jet-pipes H, screwed into bushings 1" upon each, as clearly shown in Fig. 5. The various shafts and pipes are provided at their points of junction with the steam-pipe F, or near the same with cut-01f valves q, and all find an outlet by way of the waste-pipe K, at the opposite end of the apparatns.
The cylinders B are provided along their lower faces at points intermediate between the jet-pipes H with perforations p, and L is a curved drip-pan below the said cylinders, inclined from each end to a waste-pipe, 0, which leads out through the bottom of the 63.86.
The screw-conveyers C are provided with pulleys n on the outlet ends of their shafts, and are rotated by means of belts m, connecting the pulleys n with pulleys n on the corresponding ends of the shafts of the central screw-conveyers of the drier.
The construction of the cylinders B and their attendant parts comprising the drier is as follows: The lower faces of the cylinders B are provided with perforations p, and flues M, semicircular in form, fit close against the cyl inders covering the said perforations.
The hollow shafts of the screw-conveyers C are provided with perforations s, and each is connected by means of a pipe, I, having a packing-joint adapted to permit the revolution of the conveyer with a hot-air shaft, N. Branch pipes k from these hot-air shafts lead also into the fines M, which latter are closed at their opposite ends, and thus open only into the cylinders B through the perforations p.
O O are horizontal pipes, one above each of the cylinders B of the drier, opening through the case A at one end and leading into a draftflue, P, at the other; and i i are short pipes sloping in the direction of the draft, as shown in Fig. 1, leading from the pipes 0 into the tops of the cylinders B.
The operation is as follows: Steam is admitted, by way of the pipes F, into the interior of the screw-conveyers C, and also into the pipes G and gates of pipe B. At the same time hot air is forced, by way of the standpipes N and branch pipes thereof, into the hollow perforated shafts of the screw-conveyers O, and into the fines M. The machinery having been set in motion, the material to be cooked is fed from suitable hoppers into the cylinders B by way of the chutes t, when it is immediately taken up by the conveyers therein and carried along until it reaches the chute '1), when it drops into the uppermost cylinder of the drier, along which it passes until it falls into the next cylinder, and so continues to do until it emerges from the discharge '0, as described in my former Letters Patent. While passing along the cylinder B it is subjected to the action of steam passing into the interior of said cylinder both through the perforations sin the blade of the conveyer and through the jet-pipes H.
Those varieties of grain requiring a greater degree of cooking should be fed into one of the cylinders B, and those requiring a less into the other, and the flow of steam so regulated by means of the valves q as to admit a proportionately greater volume into the latter cylinder than the former, or else the flow either through the conveyer or the pipe G may be wholly cut off, and steam admitted only through the other. The steam finds an outlet from each into the exhaust-pipe K, and the moisture which collects on the bottom of the cylinder B drips through the openings 10 into the pan L, and is carried off by the pan 0.
Upon entering the drier, and while passing back and forth through the cylinders of the same, the cooked material is subjected to the action of hot air both from within by way of the perforations s in the shafts of the conveyers and from without by way of the perforations 10, leading from the fines M. The gates of pipe E add still further to the heat to which the grain is subjected, lying, as they do, close to the cylinders.
If desired, screw-conveyors like those in the cooker-that is, with hollow blades as well as hollow shafts-may be used also in the drier with or without the addition of perforations in the shafts. In this cae, of course, hot air would be passed through them instead of steam. The shaft as well as the blade may be perforated when used in the cooker also, if preferred. It should be remarked that the chief feature of the conveyer 0 lies in the intercommunicatin g hollow shaft and blade, and that the perforations therein might, under certain circumstances, as in the drier, for example, be wholly dispensed with.
The vapors which are created within the cylinders B by the drying process pass into the pipes 0 through the oblique tubes i and escape from the apparatus by way of the draftflue P.
If desired, a forced current may be created through the pipes 0 and draft-flue P by connecting the former with the hot-air shafts N, and thus accelerating the escape of the vapors; but it i not thought that this will be found necessary.
What I claim as new, and desire to secure by Letters Patent, is
1. In a feed-cooker, the combination of the cylinder B, screw-conveyer within the same, steam-pipe G, below the said cylinder, and jetpipes H, connecting the interiors of said steampipe and cylinder, substantially as and for the purpose set forth.
2. In a feed'cooker, the combination, with the hollow cylinder B, having perforations p in its lower face, screw-conveyer O, steampipe F, pipe G, and jet-pipes H, all as shown, of the drip-pan L and waste 0, substantially as described.
3. A screw-conveyer having a perforated hollow shaft, in combination with an inclosing cylinder or case, and with a pipe adapted to convey hot air into the interior of said hollow shaft, substantially as described.
4. In combination with the cylinder B, having perforations in its lower face, and with a screw-conveyer within said cylinder, the flue M, pipe 7:, for conveying hot air into said flue,
and draft-flue P, communicating with the in- 0, tubes '5, and draft-flue P, the whole being terior of the cylinder B, the Whole being conconstructed and arranged to operate substanstructed and arranged substantially as detially as described.
